Fibromyalgia is a long-term condition associated with widespread pain, tenderness, fatigue, and changes in sleep and concentration. Many patients describe it as feeling “sore all over,” even on days when they have not done anything physically demanding. Others notice that their nervous system feels on high alert, with heightened sensitivity to stress, touch, or sensory overload.
While the exact cause is not fully understood, fibromyalgia is often linked to changes in how the brain and nervous system process pain signals. That can make normal inputs feel amplified. Symptoms may also overlap with inflammatory patterns, sleep disruption, hormone shifts, or metabolic stress, which is why a one-note plan often falls short.
